I've been reading between 20-40 books a year. But to address your real concern: I think we just need to make peace with only sampling a tiny fraction of what the world has to offer (literarily and otherwise). You can't visit every town, try every food, learn every skill, or even keep up with the rate of publications within the small niche that you are most interested in. So, rather than completing a list of all the things you "should read", I think the goal should be to try to continuously marinate your mind in the interesting ideas from books you enjoy. That is really the best we can do, but I think it could also lead to a life well lived if you find contentment in the journey rather than the destination
